Summary

A computer model developed recently to determine the performance of free-displacer Stirling cryocoolers was extended to include an optimization routine. This was applied to a two-stage, free-displacer Stirling cryocooler to determine the optimized dimensions for the displacer. The design parameters taken for the optimization were the diameters and stroke of the 1st and 2nd displacer. Based on the results of the optimization, a two-stage displacer was fabricated. The performance of this machine was evaluated under different working conditions. The agreement between the predicted and experimental results was found to be very close.
